Specification of Letters Patent.

Patented Apr. 13, 1915..

@riginal application filed December 26, 1912, Serial No. 738,539.Divided and. this application filed December T0 all whom it may concernBe it known that L-ARVID F. CAnLrN, a citizen of the United States, andresiding at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Mechanical Fans, ofwhich the following is a specification, such as will enable thoseskilled in the art to which it appertains to make and use the same.

This invention relates to mechanical fans, and the object thereof is toprovide an improved device of this class which may be secured to avertical support of any kind and turned or adjusted into diiferentpositions and be operated by a cord suspend-ed there-V from for theconvenience and comfort of a person sitting in a chair adjacent to thesupport, and with these and other objects in view, the inventionconsists in a device of the class specified constructed and operating ashereinafter described and claimed.

The invention described and claimed here in is an improvement on thatdescribed and claimed in a prior application for Letters Patent of theUnited States filed by me December 26, 1912, Serial No. 738,539.

rThe present invention is fully disclosed in the followingspecification, of which the acj companying drawing forms a part, inwhich the separate parts of my improvement are designated by suitablereference characters in each of the views, and' in which- Figure 1 is asectional side view of my improved fan device and showing the same connected with a vertical support ;-Fig. 2 a partial section on the line2--2 of Fig. 1 with parts broken away, and g-Fig. 3 aview similar toFig. 1, but showing only parts of the construction, and showing saidparts on an enlarged scale.

1n the practice of my invention, as shown in the drawing, l provide asuitable box or casing a the hack of which is provided with a raisedattaching member a2 forming part of the means for securing the fan to aver tical support. and the bottom of the casing a is provided with anoblong slot or opening a4.

In the back part of the casing a are two vertical partition plates a5and as forming a spring chamber a7 and a back chamber as, and mountedcentrally and longitudinally in said casing, and passing through thechamber a7 is a shaft Z2 which projects Serial No. 805,491.

through the front partition plate a, and into the chamber as, and aplate spring b2 1s secured in the bottom of said chamber and bears onthe end of the shaft o, and said shaft is longitudinally movable to aslight i extent.

Mounted on the shaft b within the main compartment alo of the casing aand secured to said shaft is a drum c. The drum c may be secured to theshaft b by solder, as shown at c2, or in any other way, and secured toone .end portion of said drum and wound therein is a cord CZ one endportion @Z2 of which is passed out through the slot or opening at.

Mounted on the front end portion of the shaft b adjacent to the frontwall a9 of the casing a is a gear wheel e the inner side of which isprovided with a ratchet f which is secured thereto and provided withteeth on its inner face, and secured to the shaft b between the ratchetf and the corresponding end of the drum c is a radial pawl g having anose which operates in connection with the teeth of the ratchet f.

l/Vithin the spring chamber al is placed a strong 'helical spring la,one end of which is secured to the casing a, and the other to the shaftb, and mounted in the bottom part of the front wall a of the casing a isa fan shaft i, the inner end of which is provided with a pinion 2 whichmeshes with the gear e en the shaft b, and the other end of the shaft z'is provided with a fan y'.

In the use of my improved fan device, it is connected with a verticalsupport k of any kind or class and to which is secured a curved arm 7a2provided with a longitudinal slot k3, and the attaching member a2 at thetop of the casing a is provided with a flat foot piece m through whichis passed a screw m2 provided with a thumb nut m3.

The back of the casing a is also provided with a downwardly directedattaching member n, and secured to the support la is a bracket plate ohaving an outwardly directed and curved top piece 02 provided with anopening 03, and the attaching member n is provided at its end with aneck at which is passed through the opening 03 and provided with a heador nut o5, and by means of this construction, the fan device may bemoved outward or from the support lc and adjusted in any desiredposition between that shown in full lines in Fig. 1, and that shown indotted lines, and the fan device may be also .rotated laterally or inthe direction of the arrows m and m2 in Fig. 2, and adjusted laterallyinto diferentpositions.

The plate o, in the form of construction shown, is secured to thesupport by an eye screw p with which is connected a guide pulley,- -orsimilar device, p2, and the end Z2 of the cord d, is passed through saidguide pulley and may be manipulated for the purpose of operating the fanj by a person sitting or standing adjacent thereto.

In the construction shown, the fan j is mounted parallel with the frontof. the casing a, but my invention is not limited to this relativelocation of said fan, and said fan may be placed in any desiredposition, and changes inY and modilications of the other features otconstruction herein shown and described may be made, within the scope ofthe appended claim, without departing from the spirit of my invention orsacrificing its advantages. v Y l It ywill be understood, that a pull onthe ended2 of the'eord `d will turn the drum c in one direction, andthe, fan j a corresponding directien, and this pull on the cord d windsup the spring it,V andy when said pull is released,the spring z/Willturn the drum l andV the fan j in. opposite direction, and inthis Way,the fan j .mayv be continuously operated by intermittentpulls on thecordel, orthe end d? thereoi.`

, It. will also. be seen that as the drum c is operated, there is acontinuous oscillating or vibratory movement of said drum and the shaftb, said drum and shaft being-moved Genies et this patent may be Obtainedfor in one direction by the pawl g passing over the teeth of the ratchetand in the other direction by the spring 2.

It will also be seen that the adjustment of the fan device toward andfrom the support 7c involves the idea of holding said fan device at adownward inclination to said support, which results from the fact thatthe connection of the bottom attaching member a with the plate 0, or thepart o2 thereof, has but little, if any,movement toward and from thesupport 7c, while the connection of said fan device with the arm k2permits of considerable movement of said device toward and from saidsupport.

Having' fully described my invention what l claim as new and desire tosecure by LettersPa-tent is5 In an apparatus of the class described, asupport, a slotted arm connected with said support and projectingtherefrom, a bracket secured to said support below said arm, and a fancasing the back of which is provided with a top attaching memberslidably and rotatably connected with said arm and the bottom of whichis provided with an attach-V ing member rotatably connected with saidbracket.

In testimony thatl claim the foregoing as my invention I have signed myname in presence ci the subscribing witnesses this-x 6th day of December1913.
